Pink material when using 2 x PBR (Principled BSDF) materials into a mix shader w/Eevee
I believe the limit for EEVEE is 24 textures per material. In cycles, you can get around the limitation by enabling &quot;open shading language&quot;, but I think in eevee, you're stuck. In the end, it doesn't matter what the &quot;theoretical&quot; limit is - If you hit a point where adding a new texture to the graph causes it all to turn pink, you just have to find some other way around it, such as using a texture atlas.
